Install Agent Skills into all 3 AI CLIs, and use Bun instead of npm

Adds scripts/install-skills.sh: pulls this repo's extensions/ skill
bundles (SKILL.md-format) at workspace startup and installs them into
Claude Code (~/.claude/skills), GitHub Copilot CLI (~/.copilot/skills),
and Antigravity CLI (~/.gemini/config/skills). Every env gets the common
awesome-skills-plugin bundle; COBOL/3D/TTRPG additionally get their
matching skill(s) from custom-specialty-plugin via a per-template
SPECIALTY_SKILLS value.

Each template also installs Bun via a coder_script and hooks ~/.bun/bin
onto PATH in .bashrc (the bun.sh installer doesn't reliably do this in a
scripted shell). The CLI setup wizard now uses `bun install -g` instead
of `npm install -g` for GitHub Copilot CLI and Claude Code CLI.

All six templates re-validated with terraform init/validate against the
real coder-server container on octo-winsrv.
